Google-owned Motorola Mobility is appealing the US International Trade Commission's dismissal of a complaint filed against Apple, according to newly-published court documents discovered by FOSS Patents. A single patent was left in the complaint at the time of the final ruling, one involving using a proximity sensor to disable a touchscreen when a phone is held close to a person's ear. It's not clear what basis Motorola might be pursuing for the appeal.

The motion is in fact Motorola's second appeal in the case. Last September Motorola appealed the dismissal of three patents from the complaint, and that process is still ongoing. Apple has since intervened, submitting answering briefs earlier this month as part of its support for the ITC's decision. Before a hearing can be scheduled, Motorola is expected to file a reply to Apple.
